Hillary Clinton and Donald Trump are deadlocked in the swing state of New Hampshire – a tightening from just a month ago when Clinton had a 2-point edge, a new Suffolk University/Boston Globe poll shows.

Here's the breakdown:

Clinton: 42 percent.

Trump: 42 percent.

Independent nominee Gary Johnson: 5 percent.

Grenn Party nominee Jill Stein: 2 percent.

Undecided: 8 percent.

Refuse response: 1 percent.

"Hillary Clinton has lost a couple of points since October, but Donald Trump hasn't gained them," David Paleologos, director of the Suffolk University Political Research Center in Boston, said in a statement.

"The remaining undecided voters and the number of people who cast a ballot for a third party candidate will determine the outcome as both Trump and Clinton seek to win 48 percent of the New Hampshire vote, which should be good enough to win the state."

According to the poll, voters were split on the impact of the letter sent by FBI Director James Comey to Congress informing them the FBI was reviewing new emails related to Clinton's email server probe.

Nearly 49 percent said the new revelations made them less likely to support Clinton; 45 percent said the revelations were overblown and would not affect their vote.

Among independent voters in New Hampshire, 52 percent said the revelations made them less likely to vote for Clinton, while 40 percent said it would not affect their vote.

The poll of 500 likely voters in the state by landlines and cellphone had a margin of error of plus or minus 4.4 percentage points.
